DC Cherry blossoms reached peak bloom on Sunday March 17th, a few days earlier than the National Parks Service(NPS) predictions. NPS says the trees around the National Mall and the Tidal Basin reached peak bloom on Sunday afternoon ahead of schedule.
According to NPS, the peak bloom date is defined as the day when 70% of the Yoshino Cherry (Prunus x yedoensis) blossoms are open. Peak bloom varies annually depending on weather conditions. The most likely time to reach peak bloom is between the last week of March and the first week of April. Extraordinary warm or cool temperatures have resulted in peak bloom as early as March 15 (1990) and as late as April 18 (1958).
The Yoshino trees typically bloom for a period of several days. The length of the blooming period depends on weather conditions. Cool, calm weather can extend the length of the bloom, and a rainy, windy day can bring an abrupt end to the ephemeral blossoms. A late frost can prevent the trees from blooming at all.
